Keywords: Orcad, Capture, 386+, Windows, read, reading

Urgency: Standard

General Description:Often an engineer will need to read an OrCAD SDT 386+ design into capture for Windows.This usually happens if an existing SDT 386+ design must be updated, or if the engineerreceives the SDT 386+ design from a colleague.

2. Groups and timing specifications: TIMEGRP and TIMESPEC pipe-text:In SDT-based Xilinx designs, library symbols were grouped and associated through SDT part fields and TIMEGRP pipe-text, and timing specifications through TIMESPEC pipe-text. Replace pipe-text with the new TIMEGRP or TIMESPEC symbols available from the appropriate XC<family>.OLB schematic library.

3. Part targets: PARTTYPE pipe-textIn SDT-based Xilinx designs, pipe-text was used to target the schematic work sheet to a specific Xilinx component. Capture does not facilitate this function; however, you may choose a specific target architecture and package for a project created by the XACTstep Design Manager.

See the "Getting Started" chapter in the Xilinx Design Manager Flow Engine, Reference/User Guide for more detail.

4. Global attributes: GLOBAL pipe-textIn SDT-based Xilinx EPLD designs, pipe-text was used to specify compiler and fitter optimization controls. Capture does not facilitate this function; however, you may establish global attributes for a project created by the XACTstep Design Manager.

See the "Implementation Options" chapter in the Xilinx Design Manager Flow Engine, Reference/User Guide for more detail.

SDT 386+ stores designs as schematic files(.sch) and library files(.lib). Also, a configuration file named SDT.CFG contains necessary information, such as what SDT 386+ libraries are required by the schematics.

Place the schematics, user libraries, and SDT.CFG into a directory. You may need to adjust the SDT.CFG information, such as PLIB=... so that the paths are correct. You can edit SDT.CFG in a text editor, such as Notepad.
